Abstract

Abstract : It has been thought that water is detrimental to perovskites, causing degeneration due to their ionic structures. In article number 1901994, Wen Li, Wei Yan, Weiqing Yang, and co‐workers unexpectedly find that 3D all‐inorganic perovskites are exfoliated by water molecules and transformed into more intrinsic stable quasi‐2D nanosheets in complete water conditions instead of leading to decomposition failure. This finding may not only provide a new path to investigating the intrinsic stability of all‐inorganic perovskites, but also broadens the application of perovskites.
